Georgia, have invented a. new 'and Improved Machine "foraj hereby "declare" n n t clear,`a`nd exact description of the same,`.ref erencebeing h d to` th "annexed drawings, f `nnalringl'a `p f whichi ofiny improve `ac t n 1 tion "being through thee end view of doV 11g Cotton; and" I do e following is` a full,

\ This invention relates to anew and improved machine for cleaning cotton, and consists, in the employment or use of a feed 1 card. andtwo brush rollers; arranged 'and operating as lwill be hereafter fully shown n and described... n n n To enable othersskilled in the art, to make `and use-my invention, I will proceed to "describe its construction and operation.

A represents a casefor box, having within it,at its lower part7 a roller, B, having teeth i (0:)1 vsomewhatcurved` projecting from lits n periphery; and C is a screen formed-of n curved bars, for wires, placed at one side, and rather below the center of the roller, `as shown clearly `in both figures. `The screen `@'"extends entirely across box A, as shown in 1Fig.2.` Directly underneath t f an inclined perforated board, or i shown in bothy figures.` v `E is an inclined board box, to the lower end of which the upper ""ends of thebars, or wires composing the fscreen are secured seeFig. 1. This board n is bisected and partly removed in Fig. 2,1 F is a roller having its periphery covered with a card (o) the teeth of which are about one eighth of an inch long,regularly curved i their ends, and tapering regularlyto their ends`.` The roller F is placed a short distance above the roller B and rather `at one side of i it see Fig. l. The teeth (a) of the roller B the` screen C there is sieve D at one", end of the from theleatherin which they are fixed to do not come in contact with the teethof card (b) ofroller F. yThedistance between them should be about one half of `an inch.

G is a brush roller having teeth (c) and brushes placed alternately on its peripht, t with thecasing removed in order to `show the interior.`

ery, as shown in Figs. 1 and 2. Thebrushes donot touch the rollerMF," the distance between" the brushes (el) and the teeth of card ofroller vF should be about three `thirty second (3/32) `parts of aninch; and

theteeth (c) do not project quite so far n from` the roller Gr as the brushes Fig, 1.

The brush rollerG is placed above the card i 4roller F and rather at one side.l

` His a roller having brushes (e) upon its periphery.` "The roller H is placed abovethe card roller F and rather at one side as shown in Figfl. `-The brushes (e) as theroller ro tates come in contact with the card roller F.` I is an inclined plate or board placed over the roller B between it and the roller G. See broth"figures,` i f l J is a curb placed B, F. One end ofthscurb is attached to the inner end of the inclined board D and the opposite end is inclined and forms a discharging board. The curb J is directly un- 1 derneath.` The stroke of these brushes aided by the current of wind generated by roller G eifectually separates the `seed and dirt roller F is carried around "with` vthat roller until itmeets roller H. y

The roller H` which `rotates in a reverse direction from the other rollers, brushes the cleanedcotton from the cardroller F, and the cotton passes down the passage N `and out of the box A.

In working this machine the speed of rollers B, and F should be the same. The number of revolutions in a given time should depend o-n the size of the cylinders and the cotton to be cleaned. y The speed of brush rollersG and H should be the same, and the speed of Gr and H .should be from four to six times greater than the speed of B and F;

` This machine `does its work eiciently, isgnot expensive to manufacture, and may be adapted to clean perfectly the various kinds of cotton.

underneath the 'rollers '75 The rollers, B, F,are curved to correspond u to the circular form of the rollers as clearly shown in Fig. l.

K is a curb at the upper part of the box A placed over the card roller F and between the rollers G, H. This curb is so curved as to be concentric with the rollers F Gr H see Fig. l.

L is a covering placed over the upper part of the box A.

INI is the vfeed passage or'throat of the machine, and N is the discharge passage.

Motion is communicated to the several rollers by means of pulleys O and belts I) shown by dotted lines in Fig. 1. The edges of the pulleys are seen in Fig. 2. The pulleys are placed upon the axes of the rollers on the outer side of boX A gear wheels may be substituted for pulleys if desired The rollers B F G rotate in the direction as shown by arrows l in Fig. 1. The roller H in a reverse direction as shown by arrows 2 in Fig. l.

Operat-ion: The cotton to be cleaned is placed in the throat M of the machine, and the roller B carries it around upon the card roller F. The teeth (a) of the roller B insert themselves in the mass of the cotton, shake and separate it, as it is rais-ed to F. The teeth of the card on roller F insert themselves in the fibers or wool of the cotton and raise it until it comes 1n contact with brushes (el) on roller Gr. The cotton is spread over the whole length of roller F, but the seed and dirt will not enter within the teeth of the card (b), but are thrown on the outside of the card, and exposed to the do-wnward stroke of brushes (d) on roller G.

I am aware that card clothing has been used with a rotary brush in a cotton gin and therefore I do not claim them separately or combined; but

What I claim as my invention and desire to secure by Letters Patent is- The combination of the beater B, card cylinder F, brushes G and H and plate .I when arranged substantially in t-he manner described and set forth.
